The impedance of PCB circuit board refers to the parameters of resistance and reactance, which act as obstacles to AC power. Impedance processing is essential in the production of PCB circuit boards.

For the electronics industry, according to industry surveys, the most fatal weakness of chemical tin plating is its susceptibility to discoloration (such as oxidation or deliquescence), poor solderability that makes it difficult to solder, high impedance that leads to poor conductivity or unstable overall board performance, and easy tin growth that can cause PCB circuit short circuits, burnout, or ignition events.
